Close (Choice)

Provide the Close choice in the window menu of every window.

In a secondary window, use the Close choice as a push button instead of Cancel if Close would be more appropriate or less ambiguous.

Provide a Close choice in the File menu if the window can be closed independently of other primary windows.

Provide the Close choice as a push button in a secondary window if the window is used only to present status information to the user.

If the effect of activating a choice or choices in a secondary window is irreversible, then the Close choice can replace the Cancel choice after the first irreversible action.

When closing a window, save its state (including its position, size, dependent secondary windows, and associated messages that are currently displayed) so that they can be restored if the window is opened at a later time.

When a user activates the Close choice for the last primary window displayed for an application, remove all dependent secondary windows and exit from the application.

When a user activates the Close choice for a window, remove the window and any dependent secondary windows.

Use a Close push button to close an in-progress message window without affecting the task in progress. Do not terminate the task when a user presses the Close push button in an in-progress message window.

If information in a primary window could be lost when the user activates the Close choice, display a warning message.

If information in a secondary window could be lost when the user activates the Close choice, do not display a warning message.
